scrapy包安装问题
-
Scrapy是一个纯python的包，依赖如下关键包：
-
lxml, an efficient XML and HTML parser
-
parsel, an HTML/XML data extraction library written on top of lxml,
-
w3lib, a multi-purpose helper for dealing with URLs and web page encodings
-
twisted, an asynchronous networking framework
-
cryptography and pyOpenSSL, to deal with various network-level security needs
-
-
因安装包的过程中，可能需要某些编译环境来编译一些模块。否则会出错呦(●ˇ∀ˇ●) 为减轻工作量，去装已经编译好的包。

Tip: 32位还是64位是指python的位数，不是操作系统的！！！
